Abstract
Introduction; Pulmonary fibrosis is a frequently reported COVID-19 sequela in which the exact prevalence and risk factors are yet to be established. This meta-analysis aims to investigate the prevalence of post-COVID-19 pulmonary fibrosis (PCPF) and the potential risk factors. Methods; CINAHL, PubMed/MEDLINE, Cochrane Library, Web of Science, and EMBASE databases were searched to identify English language studies published up to December 3, 2021. Results; The systematic search initially revealed a total of 618 articles - of which only 13 studies reporting 2018 patients were included in this study. Among the patients, 1047 (51.9%) were male and 971 (48.1%) were female. The mean age was 54.5 years (15-94). The prevalence of PCPF was 44.9%. The mean age was 59 years in fibrotic patients and 48.5 years in non-fibrotic patients. Chronic obstructive pulmonary disease was the only comorbidity associated with PCPF. Fibrotic patients more commonly suffered from persistent symptoms of dyspnea, cough, chest pain, fatigue, and myalgia (p-value < 0.05). Factors related to COVID-19 severity that were associated with PCPF development included computed tomography score of ≥18, ICU admission, invasive/non-invasive mechanical ventilation, longer hospitalization period, and steroid, antibiotic and immunoglobulin treatments (p-value < 0.05). Parenchymal bands (284/341), ground-glass opacities (552/753), interlobular septal thickening (220/381), and consolidation (197/319) were the most common lung abnormalities found in fibrotic patients. Conclusion, About 44.9% of COVID-19 survivors appear to have developed pulmonary fibrosis. Factors related to COVID-19 severity were significantly associated with PCPF development.

Abstract
OBJECTIVES To explore the clinical value of minimally invasive aspiration and drainage of intracranial hematoma in the treatment of cerebral hemorrhage. METHODS Seventy-eight patients with cerebral hemorrhage who were treated in the Taian City Central Hospital and the Second Affiliated Hospital of Shandong First Medical University between June 2018 and December 2019 were selected. The patients were randomly numbered and divided into two groups by drawing lots, 39 in each group. The control group was treated with the traditional internal medicine conservative therapy, and the observation group was treated with minimally invasive intracranial hematoma aspiration and drainage. The indexes of the two groups were compared. RESULTS The efficacy rate of the observation group was significantly higher than that of the control group, and the difference was statistically significant (P<0.05). The National Institutes of Health Stroke Scale (NIHSS) score of the observation group was lower than that of the control group after treatment, and the difference was statistically significant (P<0.05). After treatment, the good recovery rate of the observation group was higher compared to the control group, and the difference had statistical significance (P<0.05). The incidence of complications in the observation group was lower than that of the control group, with a statistically significant difference (P<0.05). CONCLUSION In the treatment of cerebral hemorrhage, minimally invasive intracranial hematoma aspiration and drainage facilitates the recovery of patients, promotes the improvement of neurological function, and has a high safety profile and an ideal prognostic quality.

Clinical neurology and neurosurgery. 2022;215:107205
Abstract
Acute ischemic stroke (AIS) is a fatal and debilitating condition killing 2.7 million people each year worldwide. The most commonly used treatment modality for AIS is intravenous thrombolysis (IVT) with alteplase which is indicated for those presenting within 4.5 h of onset. Due to a lack of reliable evidence on harm or benefit, the 2019 American Heart Association/American Stroke Association (AHA/ASA) guidelines consider a history of previous intracranial hemorrhage (ICH) as potentially harmful and no longer an absolute contraindication for IVT in patients with AIS, and the U.S. Food and Drug Administration (FDA) removed chronic ICH as a specific contraindication for IVT from the label in 2015. Despite a shift in guidelines, physicians frequently face the dilemmatic choice whether to administer IVT in this subset of patients due to the risk of symptomatic intracranial hemorrhage (SICH). The benefit of IVT in such patients has not been thoroughly investigated, and there are only a few studies on the subject in the literature to date. We conducted the present meta-analysis in an aim to provide solid evidence on the efficacy and safety of IVT for treating AIS in patients with a history of remote ICH. Our meta-analysis found that IVT improves functional outcomes in AIS patients with prior remote ICH without increasing SICH or all-cause mortality. These findings may contribute to the decision-making process for IVT administration in AIS patients.

Immunotherapy. 2022
Abstract
Aim: Identify and describe published literature on the use of subcutaneous immunoglobulin (SCIG) as initial immunoglobulin (IG)-replacement therapy for patients with primary immunodeficiency diseases (PID). Methods: We systematically identified and summarized literature in MEDLINE, Embase, BioSciences Information Service and Cochrane Library assessing efficacy/effectiveness, safety/tolerability, health-related quality-of-life (HRQoL) and dosing regimens of SCIG for IG-naive patients with PID. Results: Sixteen studies were included. In IG-naive patients, SCIG managed/reduced infections and demonstrated similar pharmacokinetic parameters to IG-experienced patients; adverse events were mostly minor injection-site pain or discomfort. Three studies reported improvements in HRQoL. Quality of studies was difficult to assess due to limited reporting. Conclusion: Although studies were lacking, available data suggest IG-naive and IG-experienced patients initiating SCIG likely have similar outcomes.

Abstract
OBJECTIVE Knee arthroplasty is a major surgery with potential significant blood loss. Assess the efficacy and safety of topical administration of 3 gr of tranexamic acid (TXA) in terms of reducing blood loss in knee arthroplasty. MATERIAL AND METHOD A randomized, phase III, double-blind, placebo-controlled clinical trial has been conducted. We included 150 patients in two parallel treatment groups (75 per arm). The solution was administered topically intra-articular after cementation and prior to capsular closure. Analytical determinations were made before and after surgery to quantify blood loss. RESULTS Total blood loss (TBL) for the placebo group was 831.5 ml and 662.3 ml for the TXA group. The difference between the two groups was 169.2 ml; which means a save of 20.4 per cent; this difference being statistically significant (p<0.001). There were no differences in terms of the onset of ambulation, days of admission or Visual Analogue Scale at one month of surgery. Ten patients were rejected for presurgical urinary tract infection, metal allergy, selection failure, patellar weakening, prosthetic instability, intrasurgical tibial fracture, change of indication to unicompartimental prosthesis and a loss of follow-up. There was only one complication unrelated to the investigational drug (bladder balloon). CONCLUSION The administration of TXA topically after cementation of the prosthetic components in total knee arthroplasty in a single dose has demonstrated being safe and effective.

Journal of laparoendoscopic & advanced surgical techniques. Part A. 2022
Abstract
Introduction: Staple-line bleeding and gastric leakage are the most serious complications of laparoscopic sleeve gastrectomy (LSG). Reinforcement of the staple line is reported to be a method to reduce these complications rates, but the question of which method is preferable is a matter of controversy in the literature. In this study, we compared different staple-line reinforcement methods to assess their efficiency in preventing staple-line bleeding and leakage. Materials and Methods: Two hundred patients eligible for LSG were enrolled in the study and randomized into five groups based on the reinforcement method used during surgery: no reinforcement, oversewing using 3-0 polydioxanone (PDS) suture, oversewing using 4-0 barbed absorbable closure device (V-Lock), fibrin sealant glue, and buttress material. Intraoperative and postoperative complications were recorded and analyzed. Differences were considered statistically significant for P < .05. Results: The no-reinforcement group showed higher bleeding rates (20%), although only 2.5% of the patients required reintervention. All groups using staple-line reinforcement showed better outcomes in bleeding rates (P < .05). No statistically significant differences were observed among the groups in terms of the leakage rate, reintervention rate, intraoperative complications, and operative times. Conclusion: The reinforcement of the staple line decreased the bleeding rate in sleeve gastrectomy but did not affect the gastric leakage rate.

Abstract
Our objective was to compare the effectiveness of intravenous and enteral nimodipine in preventing poor outcome from delayed cerebral ischemia in patients with subarachnoid hemorrhage. We performed a systematic search and a network meta-analysis using the following databases: PubMed, Scopus, the Cochrane Central Register of Controlled Trials, and Google Scholar. Risk of Bias 2 tool was used to assess risk of bias of included studies. A ranking among methods was performed on the basis of the frequentist analog of the surface under the cumulative ranking curve. Published studies that met the following population, intervention, comparison, outcomes and study (PICOS) criteria were included: patients with subarachnoid hemorrhage aged 15 years or older (P); nimodipine, intravenous and oral formulation (I); placebo or no intervention (C); poor outcome measured at 3 months (defined as death, vegetative state, or severe disability), case fatality at 3 months, delayed cerebral ischemia, delayed ischaemic neurologic deficit, and vasospasm measured with transcranial Doppler or digital subtraction angiography (O); and randomized controlled trials (S). No language or publication date restrictions were applied. Ten studies were finally included, with a total of 1527 randomly assigned patients. Oral and intravenous nimodipine were both effective in preventing poor outcome, delayed cerebral ischemia, and delayed ischaemic neurological deficit. Neither treatment was effective in improving case fatality. Evolving clinical protocols over a 30-year period and the risk of bias of the included studies may limit the strength of our results. Enteral and intravenous nimodipine may have a similar effectiveness in terms of preventing poor outcome, delayed cerebral ischemia, and delayed ischaemic neurological deficit. More research may be needed to fully establish the role of intravenous nimodipine in current clinical practice.

American journal of ophthalmology. 2022
Abstract
PURPOSE To compare vitreous substitution with sulfur hexafluoride (SF6) gas to balanced salt solution (BSS) for the prevention of postoperative vitreous hemorrhage (VH) in proliferative diabetic retinopathy (PDR) patients undergoing pars plana vitrectomy (PPV) for the indication of non-clearing VH. METHODS One hundred and forty-four PDR subjects requiring PPV for the indication of non-clearing VH were enrolled into the trial. Subjects were prospectively randomized into one of two vitreous substitution groups: Group A subjects underwent 20-30% SF6 gas tamponade, whereas Group B subjects underwent vitreous substitution with BSS. The primary outcome was the incidence of postoperative VH during the 6-month trial period. Secondary outcomes were unplanned PPV for VH and best-corrected visual acuity (BCVA) at 6-months follow-up. RESULTS Ninety six subjects underwent randomization and completed 6-months follow-up. The incidence of postoperative VH during the trial period was 11.1% (6/54) in Group A (SF6) and 33.3% (14/42) in Group B (BSS) (P=.01). The incidence of unplanned PPV during the trial period for postoperative VH was 3.7% (2/54) in Group A (SF6) and 14.2% (6/42) in Group B (BSS) (P=.06). The mean BCVA was not significantly different at 6-months follow-up between groups (P=.58). CONCLUSIONS This trial indicates that vitreous substitution with SF6 gas lowers the incidence of postoperative VH compared to BSS in PDR subjects undergoing PPV for the indication of non-clearing VH at 6-months follow-up. Specialists may consider SF6 gas tamponade during PPV as a means to help reduce postoperative VH in this patient population.

Abstract
BACKGROUND AND AIMS It is unclear whether frequently used cut-off values for outcome measures defining minimal clinically important differences (MCIDs) can accurately identify meaningful deterioration in chronic inflammatory demyelinating polyneuropathy (CIDP). METHODS We used data from the IOC trial, in which sixty clinically stable CIDP patients were randomized to IVIg withdrawal or continuation. We calculated change scores of the Inflammatory Rasch-Built Overall Disability Scale (I-RODS), grip strength, and MRC sum score (MRC-SS) and classified visits based on a treatment anchor (i.e. decision to restart/increase treatment after reaching a predefined early endpoint of deterioration). The variability of scores in patients without deterioration was calculated using the limits of agreement. We defined optimized MCIDs for deterioration and specific combinations of MCIDs from different outcome measures, and subsequently calculated the accuracies of the (combined) MCIDs. RESULTS Substantial variability was found in scores of the I-RODS, grip strength and MRC-SS in patients without deterioration over time, and most MCIDs were within the limits of the variability observed in patients without deterioration. Some MCID cut-offs were insensitive but highly specific for detecting deterioration, e.g. the MCID-SE of -1.96 of the I-RODS and -2 point on the MRC-SS. Others were sensitive, but less specific, e.g. -4 centiles of the I-RODS. Some combined MCIDs resulted in high specificities and moderate sensitivities. INTERPRETATION Our results suggest that clinically important deterioration cannot be distinguished from variability over time with currently used MCIDs on the individual level. Combinations of MCIDs might improve the accuracy of determining deterioration, but this needs validation.

Comparison of Clinical Efficacy and Safety between Misoprostol and Oxytocin in the Prevention of Postpartum Hemorrhage: A Meta-Analysis
Xu R, Guo Y, Zhang Q, Zeng X
Journal of healthcare engineering. 2022;2022:3254586
Abstract
In order to systematically evaluate the clinical efficacy and safety of misoprostol versus oxytocin in the prevention of postpartum hemorrhage, this paper provides evidence-based reference for clinical medication, computerized retrieval of Chinese biomedical literature database (CBM), PubMed, Embase, Cochrane Library, and clinical trials. The retrieval period is from the establishment of each database to October 1, 2021. Published randomized controlled trials (RCTS) are included in this study. The literature is screened and evaluated according to inclusion and exclusion criteria, and meta-analysis is performed using RevMan 5.3 software. A total of 13 RCTS are included, with a total of 24754 parturients. The meta-analysis shows the average blood loss (SMD = 0.10, 95% CI (-0.11, 0.32), P=0.35), the time of the third stage of labor (SMD = 0, 95% CI (-0.07, 0.08), P=0.95), and blood transfusion rate (RR = 0.80, 95% CI (0.63, 1.02), P=0.07). However, the incidences of shivering (RR = 2.61, 95% CI (1.79, 0.81), P < 0.00001) and vomiting (RR = 2.78, 95% CI (1.85, 4.18), P < 0.00001) are significantly higher than those in oxytocin group. The effect of misoprostol on preventing postpartum hemorrhage is similar to that of oxytocin, but the incidence of adverse reactions is high, and the occurrence of adverse reactions should be closely watched in the use process. Due to the limitations of the included studies, multicenter, large-sample, and high-quality RCTS are still needed in the future to further verify this conclusion.
